Hrm.  It seems to be a real crap shoot whether this B/T stuff is going
to work or not under Linux...

Since the mouse got disconnected (not by me, but by the B/T stack) I
decided to try to disconnect the headset and connect it again.  Success,
it was connected with the adapter as MASTER:

$ hcitool con
Connections:
	< ACL 00:1A:45:1B:19:89 handle 11 state 1 lm MASTER


Then I tried to connect the mouse again.  Doing that resulted in the
headset getting disconnected and the mouse was connected:

$ hcitool con
Connections:
	< ACL 00:1F:20:0F:30:6A handle 0 state 5 lm MASTER

And then shortly after they were both connected and both as slaves.
Double yay.

$ hcitool con
Connections:
	< ACL 00:1A:45:1B:19:89 handle 12 state 1 lm MASTER
	> ACL 00:1F:20:0F:30:6A handle 11 state 1 lm MASTER

I guess the connection to the headset was still being negotiated because
the connection changed:

$ hcitool con
Connections:
	< ACL 00:1A:45:1B:19:89 handle 12 state 1 lm MASTER AUTH ENCRYPT
	> ACL 00:1F:20:0F:30:6A handle 11 state 1 lm MASTER

But then the headset reverted so that the adapter was the slave again:

$ hcitool con
Connections:
	< SCO 00:1A:45:1B:19:89 handle 1 state 1 lm SLAVE
	< ACL 00:1A:45:1B:19:89 handle 12 state 1 lm SLAVE AUTH ENCRYPT
	> ACL 00:1F:20:0F:30:6A handle 11 state 1 lm MASTER

And the mouse got disconnected shortly after that:

$ hcitool con
Connections:
	< SCO 00:1A:45:1B:19:89 handle 1 state 1 lm SLAVE
	< ACL 00:1A:45:1B:19:89 handle 12 state 1 lm SLAVE AUTH ENCRYPT

~sigh~

Am I looking for something that B/T on Linux is just not ready to
deliver yet?  Namely stable co-existence of multiple devices.
